# TESS Program G022145 Title: Searching For Planets Around High Velocity Stars To Enable Uv Transmission Spectroscopy PI: Lopez, Eric - NASA/GSFC Type: SMALL Summary: Kepler showed that the transiting exoplanet population is strongly sculpted by atmospheric escape. The best observational probe of escape is transit spectroscopy with H I Lyman alpha. However, neutral hydrogen in the ISM completely attenuates the core of the line even for the closest stars, hiding the key bound region of a planet's exosphere. High radial velocity stars offer a solution, as transit signals will be Doppler shifted out of the ISM's 100\% attenuation zone. We propose to search for large, short-period planets around 264 nearby, bright, high radial velocity stars to find planet candidates that will be suitable for Lyman alpha transmission spectroscopy with the HST. We expect to find ~5 planets, which will likely become benchmark systems for directly probing atmospheric escape. # Sector 014 targets observed (24) 121871590,289.0539,37.0734,10.42,G022145 28485882,282.2028,33.3202,7.64,G022145 392656942,288.8069,32.2221,11.04,G022145;G022198 229475021,295.2858,60.6203,11.08,G022145 233631664,284.9878,64.0532,8.54,G022145 364970161,298.2427,55.06,9.98,G022145 229690324,263.2206,54.3392,10.27,G022145;G022198 298599660,271.9606,52.7981,10.8,G022145;G022198 157543085,278.9183,40.1955,10.99,G022145 157544160,278.9043,39.063,8.67,G022145 288953549,276.7327,40.7158,9.06,G022145 394172596,289.753,41.6312,8.11,G022145;G022080;G022053;G022062 271044312,294.4753,44.9836,9.1,G022232;G022145;G022205;G022121 268319776,265.7818,85.4401,9.99,G022145;G022198 219015144,223.0162,71.6602,9.76,G022145;G022198 230074284,243.9061,70.4246,10.63,G022145 237098051,239.8628,68.3483,9.78,G022145 257081096,228.7344,74.3802,10.52,G022145 154569759,191.2119,77.6715,10.72,G022145 358615829,176.9432,78.6938,8.29,G022076;G022145;G022198;G022080 371766705,173.0999,76.6517,10.84,G022145 415017371,176.881,77.0395,8.07,G022145 417930917,186.4672,62.1827,8.8,G022145 99937206,169.9809,65.8475,7.54,G022145;G022198;G022080;G022056 # Sector 015 targets observed (15) 452639506,318.0006,24.1688,7.62,G022145 287366324,326.2835,32.1848,11.51,G022145 357175613,328.8222,32.6454,10.29,G022145;G022205 407688400,326.5931,38.2174,9.54,G022076;G022145;G022198 229475021,295.2858,60.6203,11.08,G022145 233631664,284.9878,64.0532,8.54,G022145 271044312,294.4753,44.9836,9.1,G022232;G022145;G022205;G022121 364970161,298.2427,55.06,9.98,G022145 219015144,223.0161,71.6602,9.76,G022145;G022198 230074284,243.9061,70.4246,10.63,G022145 257081096,228.7344,74.3802,10.52,G022145 165762215,231.8112,59.8587,11.18,G022145;G022198 237098051,239.8627,68.3483,9.78,G022145 154486565,185.5403,73.2495,7.33,G022145;G022238 417930917,186.4672,62.1827,8.8,G022145 # Sector 016 targets observed (24) 199508986,335.0978,46.4179,7.92,G022145 341674539,329.5366,53.7507,11.76,G022145 136027859,317.1983,47.1552,9.86,G022145 119487103,332.4324,41.0362,10.24,G022145;G022198 20573045,335.1899,29.7599,11.72,G022145 357175613,328.8222,32.6454,10.29,G022145;G022205 407688400,326.5931,38.2174,9.54,G022076;G022145;G022198 352588202,355.6398,39.2386,10.83,G022252;G022145 229475021,295.2858,60.6203,11.08,G022145 233631664,284.9878,64.0532,8.54,G022145 364970161,298.2427,55.06,9.98,G022145 285977481,309.4166,53.8419,8.2,G022145 364404889,310.4987,52.2806,10.79,G022145 63056822,319.6332,52.3918,11.39,G022145 406033320,324.8131,60.2851,9.69,G022145 229690324,263.2206,54.3392,10.27,G022145;G022198 219015144,223.0161,71.6602,9.76,G022145;G022198 230074284,243.9061,70.4246,10.63,G022145 237098051,239.8627,68.3483,9.78,G022145 257081096,228.7344,74.3802,10.52,G022145 165762215,231.8112,59.8587,11.18,G022145;G022198 199574208,248.5734,57.1688,10.16,G022076;G022062;G022039;G022145;G022240;G022069 116282879,221.6585,43.8978,8.04,G022145 27334945,213.5069,37.3257,10.9,G022145 # Sector 017 targets observed (23) 242700878,8.0023,18.9346,9.45,G022145 126998169,23.1872,20.9869,10.22,G022145;G022198 18111605,20.8118,26.5424,11.09,G022252;G022145 18278208,23.4765,27.2346,9.74,G022145 26761835,24.903,28.1118,7.08,G022145 47214447,25.7423,17.1322,11.54,G022145 252191219,17.1004,54.9115,4.95,G022092;G022145;G022133;G022032;G_NONSTANDARDMASK;G_NOPHOTOMETRY;G_SPECIAL_APERTURE_25_25 65459795,358.7738,58.193,8.46,G022145 176904207,355.0672,46.7222,8.67,G022145 127502123,6.751,37.282,8.96,G022232;G022145 352588202,355.6398,39.2386,10.83,G022252;G022145 186363552,18.2776,41.6541,6.51,G022038;G022145 196839712,19.1879,44.6706,10.56,G022145 240971617,19.163,51.8547,10.27,G022145 341674539,329.5366,53.7507,11.76,G022145 376288277,338.2826,66.2263,11.32,G022145 336168253,318.7271,76.6312,8.12,G022145 366554138,331.7134,76.4369,9.01,G022145 229475021,295.2857,60.6203,11.08,G022145 233631664,284.9878,64.0532,8.54,G022145 230074284,243.9061,70.4246,10.63,G022145 237098051,239.8627,68.3483,9.78,G022145 229690324,263.2206,54.3392,10.27,G022145;G022198
